Now that I write a few posts each day, it's made me realize something plain and simple yet very useful. In order to grow as a blogger, I had to sit down at my desk and churn out those posts, no matter what. It probably sounds so stupidly simple, but it's effective.
The only way to learn how to scale your blogging skills is by pushing beyond your comfort zone each time you write. It's very much like working out. The next time you're writing and you hit that point where you feel like stopping, push yourself just a little bit further. Are the ideas you're presenting written in a way that are clear and easy to understand? Are you making the best word choices? Tweak what you've written -- make it the highest quality post it can be -- then stop.
